The latest firmware update for EAH-AZ70W true wireless headphones
Firmware Version: JMS1ZS 01.80
Headphones capture a wider range of external sounds
New improvements within the ambient sound mode have made significant steps towards reproducing more natural sound. By redesigning the algorithms used to capture surrounding sonic elements, the headphones can now capture a wider range of frequencies than before. This has enabled a more natural sounding mix of music and surrounding sounds, and will bring a much improved ambient sound experience.
The ambient sound mode focused predominantly on surrounding voices. Only captured narrow range of sound around 1000 Hz (voices, etc.).
The ambient sound mode comprehensively captures voices and other surrounding sounds, leading to a more natural sound similar to not wearing headphones at all. Captures wide range of sound from low to high frequencies.
Reduced white noise
The amount of white noise noticeable when using the ambient sound mode in a quiet environment has been reduced.
Noise reduction rate (compared to previously): -5%
Optional blinking LED setting
The headphones’ blinking LED function can now be turned off.
*LEDs blink in default settings.
*Bluetooth blinking LED ON/OFF setting is effective only when the headphones are connected to a smartphone (when listening to music, on a phone call, when transferring firmware, etc.). LEDs will continue to blink when initially paired with a smartphone and when a call is received.
How to setup
Slide the “Bluetooth blinking LED” switch in “Setting.”
